What is the radius of a hemisphere with a volume of 45729 in, to the nearest tenth
of an inch?
Answer:
Step-by-step explanation:
Use the volume of a sphere formula and then multiply it by .5 to get half of it, since a hemisphere is half of a sphere. Doing that gives us the formula:
[tex]V=\frac{4}{3}\pi r^3\frac{1}{2}[/tex] which simplifies to
[tex]V=\frac{2}{3}\pi r^3[/tex] . Now, filling in what we were given:
[tex]45729=\frac{2}{3}\pi r^3[/tex] which simplifies a bit to
[tex]137187=2\pi r^3[/tex]. We divide by 2π to get
[tex]2183.98918=r^3[/tex] and take the cubed root on your calculator to get that
r = 27.9"
[tex]Volume= 45729in^3\\\\[/tex]
[tex]Radius=r[/tex]
[tex]2/3\pi r^3=45729[/tex]
[tex]r^3=3*45729\\~~~~------\\~~~~~~2*3.14[/tex]

The table shows two options provided by a high-speed Internet provider.
Setup Fee ($) Cost per Month ($)
Option 1 80 30
Option 2 No setup fee $40
Part 1 out of 2
In how many months will the total cost of both options be the same? What will that cost be?
In months the total cost of both options will be the same. That cost will be $.
Answer:
8 months and $320
Step-by-step explanation:
To find when 30m + 80 = 40m, isolate m.
30m + 80 = 40m
Subtract 40m from both sides.
-10m + 80 = 0
Subtract 80 from both sides.
-10m = -80
Divide both sides by -10
m = 8
To find the cost, substitute 8 as m in one of the equations.
40(8) = 320
Evaluate the expression when y= 14 and z= 6.
y+z squared

Simplify your answer as much as possible.
Answer:
400 & 2
Step-by-step explanation:
Alright, so for the first question you do 14 + 6 which = 20 and if you do 20 × 20, it equals 400.
And for the second one 14 - 12= 2.

A store manager claims that 60% of shoppers who enter her store make a purchase. To investigate this claim, she selects a random sample of 40 customers and finds that 40% of them make a purchase. She wants to know if the data provide convincing evidence that the true proportion of all customers who enter her store that will make a purchase differs from 60%. The P-value of this test is 0.0098. Interpret the P-value.
Assuming the true population proportion of shoppers who will make a purchase is 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.
Assuming the true population proportion of shoppers who will make a purchase differs from 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.
Assuming the true population proportion of shoppers who will make a purchase is 0.60, the probability of obtaining a sample statistic as extreme as or more extreme than 0.40 in a random sample of 40 customers is 0.0098.
Assuming the true population proportion of shoppers who will make a purchase is different from 0.60, the probability of obtaining a sample statistic as extreme as or more extreme than 0.40 in a random sample of 40 customers is 0.0098.
Answer:
I do believe that it is Option B
(Assuming the true population proportion of shoppers who will make a purchase differs from 0.60, the probability of obtaining a sample statistic of 0.40 in a random sample of 40 customers is 0.0098.)
Step-by-step explanation:
This sample provide evidence that the grocery store manager overstated the true proportion P-value = 0.0333.
What is p-value?In null-hypothesis significance testing, the p-value is the probability of obtaining test results at least as extreme as the result actually observed, under the assumption that the null hypothesis is correct.
here, we have,
Given data in the question:
To test whether population proportion p is overstated;
Null hypothesis H₀ : p = (75%) = 0.75
Alternative hypothesis H₁ : = < (75%) < 0.75
Now, sample proportion p" = 64 / 100 = 0.64
From the dot plot below,
we will determine the p-value for test { P(p" < 0.64)}
The number of times p"<0.64 in 150 simulations is 5
Therefore:
P(p" < 0.64 ) = 5 / 150 = 0.0333
P-value = 0.0333
At 5% level of significance;
0.0333 < 0.05
Therefore, we reject null hypothesis H₀ at 5% level of significance,

complete question:
A grocery store manager claims that 75% of shoppers purchase bananas as least once a month. Technology was used to simulate choosing 150 SRSs of size n = 100 from a population of shoppers where 75% buy bananas. The dotplot shows pˆ = the sample proportion of shoppers who bought bananas in the past month. A random sample of 100 shoppers from the store were selected and 64 bought bananas in the past month. Does this sample provide evidence that the grocery store manager overstated the true proportion? Justify your answer.

Answer:
34
Step-by-step explanation:
1. look at XV, and see that it equals 32 altogether.
WX is doubled the amount of WV. So it would be the same pattern on the other side.
2. 17*2=34
You might notice that 17-9=8, so wouldn't 34-16 be 8 as well. Nope, it would be doubled just like WX is doubled the amount of WV.
Find the value of y. 108 degrees 40 degrees. x, y, z, w
Answer:
[tex] \frac{108}{2 } = 54[/tex]
The value of y for the given circle will be 54°.
What is a circle?A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
The diameter is the longest line that can be drawn inside a circle.
In our daily life, we always see circle objects for example our bike wheel.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
In the given question by the circle theorem that if a curve makes a 2x angle then the extreme point will make the angle on circle as x.
So angle y = half of angle 108°
∠Y = 108°/2 = 54°
Angle w will also same as 54° because it also satisfies the theorem of the circle.

19- What is the equation of the line that is perpendicular to the given line and has an x-intercept of 6? O y= 4 -10 86 8 10 x --**+ 8 O y=-3x+6 O y= 4X-8 O ya x-6 |(4,2) 5) 10.
Answer:
[tex]y=\frac{4}{3}x -8[/tex]
Step-by-step explanation:
So first find the slope of the given line
-2 - 4 = -6
4 + 4 = 8
-6 ÷ 8 = [tex]-\frac{3}{4}[/tex]
The slope of a line perpendicular to another line is the opposite reciprocal of the given slope.
The opposite reciprocal of [tex]-\frac{3}{4}[/tex] is [tex]\frac{4}{3}[/tex]
So now all we need to finish the slope intercept form y = mx + b is b, which is the y intercept.
[tex]y=\frac{4}{3}x+b[/tex]
Now that they give us the X intercept, you can plug in the values (6, 0).
[tex]0=8+b[/tex]
b = -8

The equation of a parabola is y=x2–8x+14. Write the equation in vertex form.
Answer:
Step-by-step explanation:
y=x^2-8x+14
To write in vertex form, group the two x-terms to make a complete square, adjust the constant term accordingly
y = x^2-8x+16 -2
factor the first three terms on the right hand side
y = (x-4)^2 -2
This means that the vertex is at x-4 = 0, or x=4, and y=2.

Sides B & F: [tex]3 * 8 =24[/tex]
Sides C & E: [tex]3 * 5 = 15[/tex] (You get 5 inches from the edges, if you fold it into a rectangular prism, the side would have dimensions of 3x5.)

I am making two kinds of cookies: chocolate chip and lemon cookies Chocolate Chip Cookies It takes 0.250.25 cup of sugar to make a batch of chocolate chip cookies. I have 5.505.50 cups of sugar. How many batches of cookies can I make?
Answer: 22 batches of chocolate chip cookies
Step-by-step explanation:
A batch of cookies can take 0.25 cups of sugar to make.
You instead have 5.50 cups of sugar.
The number of batches that can be made is:
= Total amount of sugar available / Amount of sugar required for one batch
= 5.50 / 0.25
= 22 batches of chocolate chip cookies
